Abstract:

The objective of this thesis was to assess realistic solar electricity production potential of grid-connected photovoltaic systems in Tapiola district. Furthermore, the goal was to model the energy balance of the buildings in the area. The thesis was carried out as part of the EUE (Energizing Urban Ecosystems) project founded by RYM Oy. The thesis was made for the new business unit of Fortum Oyj.

The realistic solar electricity production potential was evaluated based on solar radiation data provided by the city of Espoo. Three filters were generated in order to eliminate roof surface areas unsuitable for solar electricity production. The energy balance examinations were carried out based on the results of solar electricity production potential by exploiting load curves and index series calculation. Moreover, a model for solar electricity production in southern Finland was utilized in the thesis.

In the light of the results it turned out that almost one-sixth of the current electricity consumption in the Tapiola district could be satisfied by the solar electricity production. In addition, it was shown that especially shopping centres and office buildings are highly potential targets to be exploited for the solar electricity production.Tämän diplomityön tavoitteena oli määrittää realistinen aurinkosähkön tuotantopotentiaali verkkoonkytketyille aurinkosähköjärjestelmille Tapiolan alueella. Aurinkosähkön tuotantopotentiaaliin perustuen oli tavoitteena myös mallintaa alueen rakennusten energiatasetta. Työ tehtiin osana RYM Oy:n EUE-projektia (Energizing Urban Ecosystems) ja työn tilaajana oli Fortum Oyj:n New Business -yksikkö.
